WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 663.508, dated December 1 1, 1 Application filed April 12, 1900. Serial No. 12.552. (No model-l T0 LLZZ whont it may concern:

Be it known that I, WILLIAM E. MONROE, a citizen of the United States, residing at Newport, in the county of Campbell and State of Kentucky, ha v'e invented certain new and useful Improvements in Window-Screens, of which the following is a specification.

My invention relates to the construction of a window-screen frame and to the manner of connecting; the wire-gauze thereto.

One of the objects of my invention is to construct a window-screen frame of duplicate metallic parts,so that the frame can be shipped in a knockdown position and readily put together by the ordinary house-fitter.

Another object of my invention is to construct the frame of sectional corners adapted to receive telescopically the side rails of the frame, which also fit each other in a similar manner, whereby the side rails may be adjusted longitudinally to fit quite a wide range of window-frame sizes.

The various features of the construction are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a plan view of a section of the frame and gauze put together ready for use. Fig. 2 is a plan view of the base corner-piece in the side frame-sections. Fig. 3 is a plan view of the finishing molding-strips. Fig. 4 is a plan view of the finishing corner-piece. Fig. 5 is an enlarged section on line so 00, Fig. 1. Fig. 6 is an enlarged section on the same line of Fig. 1 with the finishing moldingstrip removed. Fig. 7 is a perspective view of the gauze-clamping strip. Fig. 8 is a modification of the side frame-piece.

A represents the base corner-piece, which is struck up from metal and provided with outside overhanging flanges a and inside overhanging flanges a. These flanges form guards for a slideway. 13 represents side strips, which are provided with overhanging flanges b I). These side strips engage under the flanges a a and are longitudinally adjustable therein. It will be observed that these flanges a, a, and b are not bent down upon the base of the main piece. By this means the elastic character of the metal holds the parts in position, and yet allows their ready adjustment longitudinally. Each corner and each side strip and each of the end strips are counterparts, so that the description of one of these will be sufficient. The inner flange b of the side and end strips are considerably elevated, as shown in Figs. 5 and 6, so that the gauze D may be readily bent over the same.

In order to firmly hold the gauze to the frame after it has been stretched over the flanges b, I provide a spring-clamp O, as shown in Fig. 7, which is slipped on over the gauze, the limbs of the clamp spanning down each side of the flanges b, as shown in Figs. 5 and 6.

In order to protect and close the joints and to give a finished appearance to the same, I provide a finished molding-strip E, as shown in Fig. 3. It is V or trough shaped in its general outline and provided with an extended flange d, which is inserted under the outer flanges a b and then sprung down, so that the inner edge Q will bear upon the wire-gauze D, as shown in Fig. 5. The elastic character of the metal holds it firmly in place, yet allows it to be taken off by means of extraneous pressure applied thereto. After the base portions of the frame have been put together the wire-gauze is stretched over the inner flanges I). Then the metallic clamp C is applied over the gauze and flanges. I then provide a finishing corner-piece F, which is provided with marginal flanges f f, which slip under the flanges a of the corner-pieces. This cornerpiece is of such a contour as will engage over and fit down upon the molding-strips. It is provided with an extended corner-section h, provided with an orifice t' opposite the orifice j in the base corn er-piece. n represents a bolt or rivet which passes through said cornerpieces and clamps them together, and these corner binding-pieces as thus secured bind and hold all the frame-sections together.

It will be observed that owing to the telescopic connections of the side pieces B with the corner-pieces and with each other the width and height of the frame may be adjusted to a very large extent and made to fit window-frames which vary several inches in size. Another material advantage is obtained by this method of construction. The parts can be shipped knockdown to the house-fitters or su pply-houses, who can buy gauze of the right width and simply cut them in the required lengths to fit the desired size of screen.

The screen-frame is fitted to a window in suitable gnideways attached to the windowsash, which receive the flange m.

In small frames only a single side strip will be required. The corner pieces being the same on all-sized frames, a large frame is produced by simply adding additional side strips.

Fig. 8 shows a modification of the side strips, in that the inside elevated flange, over which the wire-gauze is doubled, is made of a separate piece of metal from the base of the side strip and its flange or foot is clamped by the hook-joint '0, made on the base-strip.

Having described my invention, I claim 1. A window-screen frame com posed of base corner-sections having guideways formed in each angle, side sections formed of bent metal and fitting the gnideways of the corner-pieces, a projecting flange on the inner edge of the side and end pieces adapted to receive the wire-gauze and finishing corner-pieces secured tothe base corner-pieces forbinding the sections together, substantially as specified.

2. A window-screen frame composed of base corner-sections provided with outer and inner overhanging flanges on each angle, side strips having overhanging flanges telescopically eneach other and with the angle-pieces and provided with an outer and an inner overhanging flange, a metal clamping-strip 0 adapted to engage the inner flange, a Vshaped molding-strip engaging with the outer flanges of the side sections and resting upon the inner flanges of the same and finishing corner-pieces clamped to the base corner-pieces, substantially as specified.

In testimony whereof I have hereunto set my hand.
